Functional Gastrointestinal Disorders (FGID) are the common disorders in gastroenterology which can be observed in each part of the gastrointestinal tract from esophagus to rectum. The causes of these disorders are not explained completely by recent laboratory and anatomical findings. ROME III criteria are the recognition criteria about the FGID which are divided into 6 subgroups based on 5 anatomical regions and include: 1. Esophageal 2. Gastroduodenal 3. Bowel 4. Functional abdominal pain 5. Functional gallbladder and Sphincter of Oddi disorders 6. Anorectal. Based on Iranian Traditional of Medicine (ITM) books it seems that gastric dis-temperaments have a lot of similarities with the FGID and its criteria in ROME III. In this article, discussion is about relationship between them in ITM and conventional medicine.
